QoS design for an enterprise

Let's now apply the concepts discussed in this chapter to design the DiffServ-based QoS architecture for an enterprise. The steps involved in implementing QOS are as follows:

  • Define the trust boundary
  • Define traffic types and map them into traffic classes
  • Determine the number of QoS classes
  • Assess the available hardware deployed and the queuing capabilities
  • Estimate the bandwidth required for each traffic class
  • Map the traffic classes to queues on devices
  • Implement the configurations

We will discuss these steps in detail in the subsequent sections.
